β-hydroxy carbonyl (aldol) compounds through enantioselective dehydration process was developed using a cation-binding Song’s oligoethylene glycol (oligoEG) catalyst with potassium fluoride (KF) as base. A wide range of racemic aldols was resolved with extremely high selectivity factors (s = up to 2393) under mild reaction conditions. This protocol is easily scalable. It provides an alternative approach for

preliminary efforts at developing a unique base‐ and metal‐free phase‐transfer‐mediated malonic acid thioester (MAHT) ‘activation protocol’ that efficiently generates (±)‐β‐thioesters. Our bioinspired aldol process is exceptionally mild, conducted under near neutral pH reactionconditions, does not require an inert, oxygen‐free atmosphere or anhydrous reactionconditions and is highly atom‐economic.
